Removing and Replacing Parts 4-3
Precautionary measures include disconnecting the computer from the AC
adapter and port replicator and removing the main battery, PC Cards, hard-disk
drive, memory module cover, video card cover, memory modules, and devices
in the options bay.
To take these precautionary measures, follow these steps:
1. Determine the power state of the computer.
If the system is on, go to step 2.
If you are unsure whether the system is on, shut down and restart the sys-
tem, and then go to step 2.
2. Turn off any attached peripherals, and then shut down the computer.
3. Disconnect the computer and any attached peripherals from electrical out-
lets to reduce the potential for personal injury or shock.
If the computer has an AC adapter, disconnect the AC power cable from
the electrical outlet and then from the AC adapter; then disconnect the AC
adapter from the computer (see Figure 4-3) or from the Inspiron Port
Replicator II.
